7mm 'it may concern.'

Y a subject of the King of Great Britain and This Aobject I attain in the following manner,

reference being had to the accompanying drawing, in which Figure IJ is a. vertical sectional view of a centrifugal separator' illustrating my invention; Fig. 2, is an enlarged view of the bearing; Fig. 3, is a plan view of the ball cage;

i Fig. v4r, is an edge view of the ball cage shown in Fig 3.

A indicates the base of the structure supporting the annular' shell B which is fastened to the base.

B is the cover leld in place by an arm having a conning screw b. The arm is arranged to swing on the standard b2 at one side ofthe machine so that when it is desired to remove the cover the screw b is backed oii', and the arm is turned on its pivot clear of the cover, after wlrich the cover can be removed.

Mounted in tl' e base A is tl've vertical bearing D having a flange (l in the present instance, which is securely fastened to the portieri A of the base forming the bottom of the chamber inclosed by the shell B.

Mounted in tle bearing is a vertical spindle C carrying at its upper. end the basket E, which has an elongated hub e through which the spindle extends. The spindle is reduced as shown to form a shoulder c upon which the basket rests, and a nut c confines the lbasket to the spindle. The hub y e and the bot'ton e of the basket are prefertel ably formed in one piece, the hub having a cavity eopen at the bottom and the walls of this cavlty are perforated so that steam can enter this lcavity and pass through the perforations into the interior of the basket.

Aperforated shell e3 forms the outer Wall ofl be 1t known that I, lHoMAs S. PAr'rEns0N,'

the basket and this shell is supported Aby heavy steel bands e4 in the vpresent instance. Depending from the bottom of the basket is a flangey f ira-ving wiilgsj" which forni the lades of a turbine wheel for driving the basket.

F is the steam pipev having a nozzle f2 which is so situated in respect to the said blades f that when the steam passes from the nozzle it will iinpinge upon these blades and rapidly rotate the basket. The exhaust steam passes around the outside of the basket and through the assage e2 at the center, passing into the asket and tl'lrough the 'material contained in the basket. By this means the oil and grease ywith which the. material 4is saturated orcoated is liquefied by the heat and is freed from the material by centrifugal force, passing through the openings in the shell into the outer chamber while the material is held by the shell.

G is the pipe tapped into the bottom plate A in the form of a trap, and is for the purpose of drawing oil the oil or grease as it accumulates in the bottom of the chamber.

In this type ofmachinc it is very diHic-ultI-A` lto properly su port the spindle C and to lubricate it, as t 1e tendency 1s, in all machines driven at a high speed, to throw oil the lubricant so that in many cases the bearing becomes heated and is destroyed.

Secured to the bottom of the bearing is a plate D and ,mounted on this plate, as clearly shown in Fig. 2, is a base plate I of a ball bearing. I is a cap plate and between these two lates I, Iare mounted the balls i held in t Le cage, consisting of two )erforated plates t', i connected together.l t will be noticed that these balls are so'situated that each travels in its own concentric path. The plate I has a central spherical projection i2 and the stem C has a cavity c2 in 1ts end conforming to the shape of the said projection, although in some instances the projection may be omitted and the stern may rest directly upon the flat portion of the plate I.

Mounted in the bearing d is a bushing c3 which supports the central portion. of the spindle, t ie s indle snugly fitting the lower portion d2 of t e bearin `In order to roperly ubricate thebearing I provide a lu ricant reservoir M4 mounted on a bracket at one side of the machine, on a line with the upper portion of the bearing D.

In the plate at the base of the bearing is a, central opening d? and communicating with this opening is e pipe m. leading from the botn tom of the reservoir M, and in line ,with the o ening d3 is en opening 5,3 in tl'ie plete l. eo t at the lubricant will pass into the bell. rece and from the Dall race up throughthe bem ing D to the upper end. Formed in the bearinOv in the present instance is e channel rnl Whio oommum'oatee'et n', with e, pipe m leading from this point through 'the bottom of the reservoir M to @peint on. a line with or slightly below the upper Peltier! of the bearing D.. By enteringv the pipe' m et the 'center of the bearing the centrifugal eotion will not drive the lulnicent away from the bearing but the rotation 4et the 'belle end 'the upper plete, as Well es the spindle, will tend to drew the lubricant into the wearing and consequently creates, 'partiel yecuum in 'the reservoir M, tliie Awill eeuee the' lubricant when it reaches the enlarged orties; .f3fo the bearing to be drawn allumej 'time pasea/ge 'n and through the pioe m to tee reeeryoir, time circulating the lu rieent eed keeping the boerin( l properly lubricated et all times. Whi e ll have shown my invention ee per tioulerly a plied to a separator in which the, basket is tllrwen by e turbine engine, it will. be understood that the lmelret may lie driven in any marinier desired 'mithoegit flepmtigiig from the essentiel feature el? the invention..
